Mini Generator Has Enough Power to Run Electronics

New microengines would be smaller, last 10 times longer than batteries. It may be tiny, but a new microgenerator developed at Georgia Tech can now produce enough power to run a small electronic device, like a cell phone, and may soon be able to power a laptop. The microgenerator is about 10 millimeters wide, or about the size of a dime. When coupled with a similarly sized gas-fueled microturbine (or jet) engine, the system, called a microengine, has the potential...

EU-wide communication network to be upgraded

The European Commission has launched a call for tender for the provision of s-TESTA, a new secure communications network for the exchange of electronic data between public administrations across Europe. The new platform will replace the existing TESTA II network in mid-2005. The objective of s-TESTA (“Secured Trans-European Services for Telematics between Administrations”) is to offer a secured, reliable and managed trans-European communications platform allowing information to be securely exchanged between EU and EEA Member States’ national administrations and European Institutions and Agencies. The platform, based on a dedicated, private infrastructure, will by default provide at least one secured access...

China Sets up New Telecom Commission

China's Optical Communications Market Recovers

The optical communications market in China has pulled out of a slowdown and got back onto a firm footing in the first half of the year, according to Wang Lei, senior analyst with CCID, a consulting firm shored up by the Chinese Ministry of Information Industry. CCID predicted that the mainland optical fiber and cable market will grow by 5 per cent to 10 per cent in 2004 compared with one year earlier, basing on the fact that domestic telecom carriers were stepping up competition and building backbone networks one after another. CCID anticipated fiercer competition in the market this...

Demystify WAN link monitoring

In today’s network environment, WAN monitoring has different meanings to different people. For some, WAN monitoring is simple router queries to monitor link utilization on an ad hoc basis. For others, WAN monitoring means a distributed set of remote-monitoring agents and probes that collect and send comprehensive link statistics to a central server that stores, analyzes and displays the data. Still others view WAN monitoring as something only done during troubleshooting, where a portable device is used to capture packets “on the line” in real-time. Typical enterprise WAN networks use multiple interface types. In-line analyzers must support all these interfaces...

Sharing network analysis equipment

The most widespread method for managing network monitoring is through the use of analysis equipment, such as probes and sniffers. These devices perform a variety of critical tasks–from analyzing network traffic and troubleshooting application performance to detecting security concerns. In general, sniffers are used to “reactively” troubleshoot the network. Support staff should be able to quickly attach a sniffer to the network to resolve a problem. Probes “proactively” maintain the network with intelligent data-capture abilities. Some of the more simple versions of these devices use a command-line interface and dump captured data to the administrator’s computer screen. Through a GUI...

What is the best tool?

Keyboard/video/mouse (KVM) technology has been a part of the network infrastructure for the past two decades, with the devices evolving into a more expansive role within the data center. When evaluating approaches, analog vs. digital solutions are an important consideration. Larger organizations with multiple locations may have more network resources and may benefit from both analog and digital KVM access, whereas small-to-midsize businesses (SMBs) may only need onsite access and therefore require only analog KVM access. For a digital KVM solution to operate at peak performance, significant bandwidth is vital.

Do phone users want their m(obile) TV?

A reality show or soap opera on your mobile phone? This is the vision of top telecommunications firms, hoping that in 2006 consumers will start to sign up for new phones that can receive digital television signals. Some executives predict that full-fledged television could be the biggest mobile hit since voice calls. "Mobile TV is actually the most important application beyond voice and messaging in phones," said Andrew Cole, a vice president for consultancy A.T. Kearney. He said U.S. users alone will spend $30 billion annually on mobile TV, money that will go to telecommunications operators, equipment makers and broadcasters....

North Korea targets cell-phone 'spies'--report

TOKYO--North Korea is cracking down on the use of mobile phones in border areas in a bid to stop smuggling and "spy activities," Japan's Kyodo news agency said on Monday. Citing a document obtained by a Japanese non-governmental organization, Kyodo said Pyongyang had defined political textbooks and state-determined price lists for everyday goods as contraband, alongside rare metals and agricultural produce. Transmission of confidential information, providing information about the whereabouts of people, or assisting in the delivery of letters to foreigners are defined as spy activities in the document, Kyodo said. "Some residents have contacts with people in neighboring countries...
